When Thomas Edison said ‘one percent inspiration, ninety-nine percent
perspiration,’ he was primarily talking about the hard work that goes into
turning the bright idea into a usable and marketable product.

Refining is often an iterative process of testing and improvement, with rigorous
and creative thought at every stage. Dreamers often hate this stage as it can
lack the joys of raw creation, but this is where the real gold of true value is
created, where inventions that better mankind (and, hopefully, your pocket!) are
crafted.

Each iteration of refinement may itself involve a complete or partial TAO loop
of invention, as you discover and resolve successive problems and
contradictions.
